That's my guess too. With digital IO, you can say "drive an output pin high". In the old days that was done with transistors (TTL, later CMOS). It's seems lo

That's my guess too. With digital IO, you can say "drive an output pin high". In the old days that was done with transistors (TTL, later CMOS). It's seems logical if you had hardware connected to a digital IO, you could refer to the software as driving the hardware.
